Nebushasban
(Heb. Nebushazban', נְבוּשִׁזְבָּן[written in the text with a small final n, for which some copies have, perhaps by error, a z], from Nebo, and Persian chesban, " votary," i.e., adorer of Nebo; Sept. omits, but some copies have Ναβουσεζβάν orΝαβουσαρσελχίμ; Vulg. Nabusezban), the Rabsaris (q.v.) or chief chamberlain of the Babylonian court, sent by Nebuchadnezzar, in connection with the two other chief dignitaries, Nebuzaradan (the Rab-tabbachim, or chief of the body-guard) and Nergal- sharezer (the Rab-mag, or head of the Magians), to release Jeremiah from prison on the capture of Jerusalem (Jer_39:13). B.C. 588. "Nebu- shasban's office and title were the same as those of Ashpenaz (Dan_1:3), whom he probably succeeded. In the list given (Dan_1:3) of those who took possession of the city in the dead of the night of the 11th Tammuz, Nebushasban is not mentioned by name, but merely by his title Rab-saris. So at the Assyrian invasion in' the 'time of Hezekiah, Tartan,? Rab-saris, and Rab-shakeh, as the three highest dignitaries, addressed the Jews from the head of their army (2Ki_18:17). Possibly these three officers in the Assyrian court answered to the three named above in the Babylonian."
